摘要：
The microstructure of Fe85Ga15 ribbons, which show up large magnetostriction, has been investigated by means of XRD and TEM from room temperature up to 1000 K. It was found that the structural features of the crystal at room temperature resembles the modified D0(3) tetragonal structure and the inserted domains of about a few nanometers commonly appear in the materials along [10 1] zone-axis direction. In-situ heating TEM observations show that the high-temperature annealing could evidently affect the microstructure of Fe85Ga15 ribbons. (c) 2005 Elsevier B.V. All rights reserved.
